Description
CROSS-REFERENCE TO RELATED APPLICATION(S)
[0001] This application claims the benefit of Korean Patent
Application No. 10-2017-0161704 filed with the Korean Intellectual
Property Office on Nov. 29, 2017, the full disclosure of which is
incorporated herein by reference.
TECHNICAL FIELD
[0002] One aspect of the present disclosure relates to a cosmetic
composition, and more specifically to a cosmetic composition for
skin moisturization including, as an active ingredient, a composite
seawater extract obtained by mixing each of seawater extracts of
Brussels sprouts, lima beans and artichokes. Another aspect of the
present disclosure relates to the use of a mixture of a seawater
extract of Brussels sprouts, a seawater extract of lima beans, and
a seawater extract of artichokes, as an active ingredient, in the
preparation of a cosmetic composition, preferably a cosmetic
composition for skin moisturization. Yet another aspect of the
present disclosure relates to a method for maintaining the skin
moisturizing ability of a subject and/or improving the
moisturization state, including the step of locally applying a
cosmetic composition containing, as an active ingredient, a
composite seawater extract of Brussels sprouts, lima beans and
artichokes to the skin of a subject.
BACKGROUND ART
[0003] Skin is largely divided into three layers: the epidermis,
the dermis and the hypodermis, and plays a role in protecting the
human body from physical and chemical stimulations from the
external environment. Especially, the skin regulates that about
65-70% of water possessed by the human body is evaporated out of
the body. Among them, the epidermis is sequentially divided into
the stratum corneum, the stratum granulosum, the stratum spinosum
and the stratum basale, and the stratum corneum of the epidermis
contains about 10 to 20% of water, and prevents water inside the
body from evaporating and blocks excessive penetration of materials
from the outside by being located at the outermost layer of the
human body (J. Invest. Dermatol. 80(Suppl.), 44-49. 1973). The
water-soluble natural moisturizing factors (NMF) are present at
high concentrations in the cells of the stratum corneum, and these
factors not only function to provide flexibility to the skin, but
also help to maintain water at suitable level (J. Invest. Dermatol.
54, 24-31, 1970). However, due to a variety of reasons, including
changes in the environment or changes in life patterns, various
stresses caused by social life and environmental pollution,
frequent cleansing due to makeup and natural aging of the skin with
aging, and the like, the water content of the stratum corneum
decreases and thereby, the skin tends to become dry, the surface of
which becomes rough, and the skin loses luster and may look dull.
Thus, the importance of solving the problem associated with skin
moisturization has been increasing.
[0004] Thus, various cosmetic raw ingredients having a skin
moisturizing function are being developed. In the case of chemical
raw materials, there are problems such as causing side effects
including skin allergy or skin trouble. In the case of animal raw
materials, the use of animal raw materials is rapidly decreasing
due to a decrease in consumer preferences and the controversy of
mad cow disease, and the like. Thus, environment-friendly raw
materials such as plant-based raw materials have gained much
interest.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0014] Unless otherwise defined, all technical and scientific terms
used herein have the same meaning as commonly understood by one of
ordinary skill in the technical field to which the present
disclosure belongs. In general, the nomenclatures used herein are
those well-known and commonly used in the art.
[0015] Hereinafter, the cosmetic composition according to the
present disclosure will be described in detail.
[0016] As used herein, the term "about" used to express the volume,
time (duration), concentration, content, area, temperature, and the
like means that there is a maximum tolerance of 10% in the
corresponding numerical value or range.
[0017] The cosmetic composition according to one embodiment of the
present disclosure contains, as an active ingredient, a composite
seawater extract of Brussels sprouts, lima beans and
artichokes.
[0018] Brussels sprouts used as an active ingredient in the
cosmetic composition of the present disclosure is also referred to
as Brassica oleracea L. var. gemmifera Zenker.
[0019] Brussels sprouts are known to have superior storage period
and significantly high contents of nutrients such as proteins,
calcium, phosphorus, iron, vitamin A, vitamin C, and the like
compared to common cabbage.
[0020] Lima beans used as an active ingredient in the cosmetic
composition of the present disclosure are the oldest type of beans
in South America and are native to Central and South America.
[0021] Lima beans, like other types of beans, are rich in protein
and low in calories and in fat and thus can be used as foods that
can give a feeling of satiety during weight control, and contains a
high content of fiber, and thereby helps prevent lifestyle diseases
such as arteriosclerosis and high blood pressure by lowering
cholesterol level in the body as well as constipation. It also
contains isoflavones, which is known to help prevent breast
cancer.
[0022] Artichoke (Cynara scolymus), which is used as an active
ingredient in the cosmetic composition of the present disclosure,
is a perennial plant that looks like a thistle belonging to the
Asteraceae family and is a plant that is characterized by a giant
flower that resembles a thistle as a giant thistle. It is conveyed
that it has been cultivated since the ancient Greek or Roman times
and used as a food. Artichoke contains saccharides that act like
insulin and thus is highly recognized for its medicinal purposes,
and is known to have a cholesterol-lowering effect in the leaves
and roots. When used as a tea, it helps to improve the diuretic
action and the liver function. In addition, it shows effects in
preventing lifestyle diseases such as potent antioxidant activity,
protective function of hepatocytes, blood glucose control and the
like, and in promoting digestion.
[0023] The composite seawater extract of Brussels sprouts, lima
beans and artichokes according to the present disclosure may be
prepared by obtaining each of seawater extracts of Brussels
sprouts, lima beans and artichokes, and mixing them, or by mixing
Brussels sprouts, lima beans and artichokes and extracting the
mixture with seawater. It may preferably be a mixed extract
prepared by obtaining each of seawater extracts of Brussels
sprouts, lima beans and artichokes, and mixing them.
[0024] The Brussels sprouts, lima beans and artichokes may be
extracted by a known extraction method for natural substances, and
the solvent used for extraction may be seawater. The amount of
seawater may vary depending on the amount of the seawater extract
of Brussels sprouts, the seawater extract of lima beans, and the
seawater extract of artichokes. For example, the seawater extract
may be prepared by adding seawater 5 to 1000 times, preferably 5 to
100 times, and most preferably 10 to 30 times the weight of each of
Brussels sprouts, lima beans and artichokes to Brussels sprouts,
lima beans and artichokes, and immersing them therein.
[0025] In this case, the extraction temperature may be 5 to
60.degree. C., preferably 12 to 30.degree. C., more preferably 10
to 20.degree. C., and extraction time is not particularly limited,
but the extraction may be carried out, for example, for 1 to 24
hours, preferably 2 to 12 hours, more preferably 4 to 6 hours.
[0026] The composite seawater extract of Brussels sprouts, lima
beans, and artichokes may be prepared by a known extraction method
for natural substances as necessary. For example, it may be
extracted by cold water extraction, hot water extraction,
ultrasonic extraction, reflux extraction, and heat extraction, and
it may be preferably extracted by hot water extraction or reflux
extraction, and the extraction can be repeated 1 to 10 times,
preferably 2 to 7 times.
[0027] The composite seawater extract of Brussels sprouts, lima
beans and artichokes may be used as a liquid by filtration, and
preferably, it may be used as a solid through a drying process such
as spray drying or freeze drying. More preferably, it may be mixed
with dextrin before carrying out spray drying or freeze drying and
dried.
[0028] In the present disclosure, the composite seawater extract of
Brussels sprouts, lima beans and artichokes may be prepared by
mixing a seawater extract of Brussels sprouts, a seawater extract
of lima beans, and a seawater extract of artichokes in a weight
ratio of 1:1:3 to 50.
[0029] Further, in order to achieve the desired effects, the
composite seawater extract of Brussels sprouts, lima beans and
artichokes may be contained in an amount of 0.001 to 40% by weight,
preferably 0.01 to 30% by weight, more preferably 0.1 to 10% by
weight based on the total weight of the composition.
[0030] In the present disclosure, considering the formulation
stability and the limited content of use based on the regulations
concerning the safety of cosmetics, when the total weight of the
composite seawater extract of Brussels sprouts, lima beans and
artichokes is less than 0.001% by weight, the desired efficacy of
enhancing the barrier function of the skin and/or improving the
moisturizing ability of the skin may be not exhibited as a cosmetic
material. Further, when the total weight exceeds 40% by weight, the
composite seawater extract may not be sufficiently dissolved in the
cosmetic formulation, so that it may not be stably mixed with other
ingredients of the cosmetic formulation, and in addition, there may
be problems in terms of safety such as excessive skin irritation
when applied to the skin.
[0031] Meanwhile, in the present disclosure, the seawater may be
common seawater, deep ocean water, lava seawater, or the like, but
is not limited thereto. Preferably, it may be seawater withdrawn
from 30 to 150 m underground (based on average sea level),
preferably 44.35 m, 86.35 m, or 126.35 m by excavating 100 to 200 m
underground, preferably 150 min Handong-ri, Gujwa-eup, North
Jeju-gun, eastern Jeju-do.
[0032] In addition, the density of the seawater may vary depending
on the temperature, pressure and salinity of the seawater, but is
usually 1000 to 2000 g/L, preferably 1002 to 1100 g/L, more
preferably 1005 to 1045 g/L. Such seawater may be those desalinated
using a conventionally known desalination method, such as flash
vaporization method, seawater freezing method, reverse osmosis, ion
exchange resin method, electrodialysis method (ED), or using a
commercially available electrodialyzer or desalter after removing
impurities such as microorganisms of seawater collected by a
sterile filter, preferably a 0.2 .mu.m filter, and preferably, it
may be those desalinated by an electrodialysis method which can
control the mineral concentration and hardness of the desalinated
seawater by varying its electrical conductivity value. For example,
when using the electrodialysis method, the desalinated seawater may
be prepared through a desalination process which removes monovalent
cations and divalent anions by adjusting the electrical
conductivity values to 8 mS/cm, 10 mS/cm, 12 mS/cm, 15 mS/cm or the
like.
[0033] The cosmetic composition of the present disclosure may
further include ingredients commonly used in cosmetic compositions
in addition to the active ingredients. For example, it may include
a conventionally adjuvant such as fatty materials, organic
solvents, solubilizer, thickeners, gelling agents, softeners,
antioxidants, suspending agents, stabilizers, foaming agents,
aromatics, surfactants, water, ionic or non-ionic emulsifiers,
fillers, sequestering agents, chelators, preservatives, vitamins,
blockers, humectants, essential oils, dyes, pigments, perfumes,
hydrophilic or lipophilic activating agents, and a carrier. In
addition, these adjuvants or carriers are introduced in amounts
commonly used in the cosmetic or dermatological field.
[0034] The cosmetic composition according to the present disclosure
may be prepared in a conventionally prepared formulation in the
art. For example, it may be formulated into solution, suspension,
emulsion, paste, gel, cream, lotion, powder, soap,
surfactant-containing cleansing, oil, powder foundation, emulsion
foundation, wax foundation, pack, massage cream, spray, and the
like, but is not limited thereto. More particularly, the cosmetic
composition may be prepared into a formulation of softening
cosmetic water, nourishing cosmetic water, nourishing cream,
massage cream, essence, eye cream, cleansing cream, cleansing foam,
cleansing water, facial pack, spray or powder.
[0035] The present disclosure relates to the use of a mixture of a
seawater extract of Brussels sprouts, a seawater extract of lima
beans, and a seawater extract of artichokes, as an active
ingredient, in the preparation of a cosmetic composition,
preferably a cosmetic composition for skin moisturization.
[0036] The present disclosure relates to a method for maintaining
the skin moisturizing ability of a subject and/or improving the
moisturization state, including the step of locally applying a
cosmetic composition containing, as an active ingredient, a
composite seawater extract of Brussels sprouts, lima beans, and
artichokes to the skin of a subject.

Example 1: Preparation of Composite Seawater Extract of Brussels
Sprouts, Lima Beans and Artichoke
[0040] 20 g of Brussels sprouts, 20 g of lima bean seeds and 200 g
of artichoke leaves were respectively pulverized using a
pulverizing device, and about 25-fold weight of seawater was added
thereto based on the weight of each pulverized product of Brussels
sprouts, lima beans, and artichoke leaves, and the products were
immersed therein at about 15.degree. C. for about 5 hours, and then
filtered to obtain each extract. The each of seawater extracts of
Brussels sprouts, lima beans and artichoke leaves were mixed to
prepare a composite seawater extract of Brussels sprouts, lima
beans and artichoke.
Comparative Example 1: Preparation of Composite Purified Water
Extract of Brussels Sprouts, Lima Beans and Artichoke
[0041] A composite purified water extract of Brussels sprouts, lima
beans and artichoke was prepared in the same manner as in Example
1, except that purified water was used as an extraction
solvent.
Test Example 1: Effect of Promoting Expression of ABCA12 Gene
[0042] The ABCA12 gene is a skin barrier-related gene, and is known
to contribute to intercellular lipid formation by participating in
lipid migration from the cytosol of keratinocytes to lamellar
granules. Therefore, in order to confirm the effect of promoting
the expression of the ABCA12 gene of the composite seawater extract
of Brussels sprouts, lima beans and artichokes according to the
present disclosure, an experiment was conducted as follows.
[0043] Human epidermal keratinocytes (HEKn, Lonza) were seeded into
a 6-well plate medium (KBM-gold, Lonza) at a concentration of
2.times.10.sup.5 cells/well and cultured for 24 hours under
conditions of 37.degree. C. and 5% CO.sub.2. Here, the composite
seawater extract of Example 1 was treated at 0.05% and 0.1% based
on the volume, and further cultured for 24 hours. The further
cultured keratinocytes were lysed with TRIzol (Invitrogen) to
isolate RNA, and the isolated RNA was purified once more with an
RNA kit (QIAGEN RNeasy kit, QIAGEN, Valencia, Calif.), and then the
quality of RNA was examined using an bioanalyzer 2100 (Agilent 200
BioAnalyzer, Agilent Technologies, Santa Clara, Calif., USA).
Thereafter, cDNA was synthesized using a Superscript Reverse
Transcriptase (RT) kit, (Invitrogen, Carlsbad, Calif.). In order to
confirm the expression level of the ABCA12 gene, real time PCR was
performed using a probe (TaqMan.TM. fluorogenic probe, Hs00292421
m1) to observe the expression pattern of the ABCA12 gene. Here, for
the analysis of the relative expression pattern for each sample,
corrections were made based on the mRNA expression level of RPL13A
(Ribosomal Protein L13a). The results are shown in FIG. 1. As a
control group, the composite purified water extract of Comparative
Example 1 was treated at 0.05% and 0.1% based on the volume to be
used, instead of the untreated group and the composite seawater
extract of Example 1. The y-axis value in FIG. 1 represents the
relative gene expression level when the gene expression level of
the untreated group was 1.
[0044] As shown in FIG. 1, it was confirmed that the composite
seawater extract of Brussels sprouts, lima beans and artichokes
according to the present disclosure greatly promoted the expression
of the ABCA12 gene, which is a skin barrier-related gene, and it
showed a remarkably excellent effect when treated at the same
concentration as the composite purified water extract of Brussels
sprouts, lima beans and artichokes.
[0045] Therefore, it was confirmed that the composite seawater
extract of Brussels sprouts, lima beans and artichokes according to
the present disclosure greatly promoted the gene expression of
ABCA12, thereby providing excellent skin barrier-enhancing and skin
moisturizing effects.
Test Example 2: Effect of Promoting Expression of mRNA of
Occludin
[0046] Occludin, a cell membrane protein, is specifically expressed
in tight junctions that play an important role in maintaining and
strengthening the barrier function of the skin. When the expression
of the occluded protein is inhibited, transepidermal water loss
(TEWL) increases significantly, and thus, it can be suggested that
occludin is highly related to water loss (Bazzoni et al., J Cell
Biol., 156(6):947-9. 2002; Furuse et al., J Cell Biol.,
156(6):1099-111, 2002; Nakajima et al., J Pharmacol Exp Ther.,
354(3):440-7., 2015; Volksdorf et al., Am J Pathol.,
187(6):1301-1312, 2017; Papakonstantinou et al.,
Dermatoendocrinol., 4(3):253-8, 2012).
[0047] Therefore, in order to investigate the effect of promoting
the expression of the occludin coding gene (mRNA) of the composite
seawater extract Brussels sprouts, lima beans and artichokes
according to the present disclosure, an experiment was conducted as
follows.
[0048] Human epidermal keratinocytes (HEKn, Lonza) were seeded into
a 6-well plate medium (KBM-gold, Lonza) at a concentration of
2.times.10.sup.5 cells/well and cultured for 24 hours under
conditions of 37.degree. C. and 5% CO.sub.2. Here, the composite
seawater extract of Example 1 was treated at 0.05% and 0.1% based
on the volume, and further cultured for 24 hours. The further
cultured keratinocytes were lysed with TRIzol (Invitrogen) to
isolate RNA, and the isolated RNA was purified once more with an
RNA kit (QIAGEN RNeasy kit, QIAGEN, Valencia, Calif.), and then the
quality of RNA was examined using an bioanalyzer 2100 (Agilent 200
BioAnalyzer, Agilent Technologies, Santa Clara, Calif., USA).
Thereafter, cDNA was synthesized using a Superscript Reverse
Transcriptase (RT) kit, (Invitrogen, Carlsbad, Calif.). In order to
confirm the expression level of the occludin gene, real time PCR
was performed using a probe (TaqMan.TM. fluorogenic probe,
Hs00170162_m1) to observe the mRNA expression level of the occludin
gene. Here, for the analysis of the relative expression pattern for
each sample, corrections were made based on the mRNA expression
level of RPL13A (Ribosomal Protein L13a). The results are shown in
FIG. 2. As a control group, the composite purified water extract of
Comparative Example 1 was treated at 0.05% and 0.1% based on the
volume to be used, instead of the untreated group and the composite
seawater extract of Example 1. The y-axis value in FIG. 2
represents the relative gene expression level when the gene
expression level of the untreated group was 1.
[0049] As shown in FIG. 2, it was confirmed that the composite
seawater extract of Brussels sprouts, lima beans and artichokes
according to the present disclosure greatly promoted the mRNA
expression of occludin, which is a tight-junction-related protein,
and it showed a remarkably excellent effect when treated at the
same concentration as the composite purified water extract of
Brussels sprouts, lima beans and artichokes.
[0050] Therefore, it was confirmed that the composite seawater
